DELIVERING A SMARTER, QUIETER ALTERNATIVE
One of the biggest challenges in the construction sector is noise pollution. To address this challenge, Wernick Power Solutions partnered with Greener Power Solutions. A battery in a hybrid set-up with diesel generators was able to meet both the operational as well as environmental requirements of the project. The result was a low-noise and low-emission set-up that perfectly met the end client’s needs.
In rural England, a large-scale infrastructure project was underway at a 400kV substation. The site required robust temporary power to support a complex modular setup provided by Wernick Hire. The installation included 28 modular bays, arranged in two levels of 14, and featured comprehensive welfare and office facilities, including drying rooms, toilets, changing areas, a canteen, and multiple workspaces. The space was designed to support over 100 engineers throughout the duration of the build.
SILENT RUNNING IN RURAL AREAS
Originally, the power solution called for two 500kVA diesel generators, with one running continuously and the other on standby. Multiple fuel tanks would be required to support this setup, with constant refuelling necessary to meet the site’s 24/7 energy demands. With Greener’s battery solution, Wernick were able to use two 200kVA generators instead, resulting in significant savings in diesel, emission and noise. The substation was located near working farms, and the surrounding community made it clear that night-time running was not an option due to noise. With work scheduled around the clock, the power system needed to be not only reliable but silent after dark.
At the core of the solution was a 336kWh battery paired with two 200kVA generators: one operational, one for standby. During daylight hours, the generator worked in conjunction with the battery to deliver steady, reliable power to the site. Once night fell, the battery seamlessly took over, ensuring silent operation without compromising performance or safety.
This approach not only eliminated the need for a large diesel generator to run overnight but also significantly reduced fuel consumption, emissions, and maintenance requirements. Since the end of September 2025 until mid-April 2025 we’ve been able to save 60599 litres of fuel, 196 tonnes CO2 and 925 kg NoX.
The site team praised the system’s uninterrupted overnight performance, and the quiet operation played a key role in maintaining positive relations with nearby landowners and residents. In addition to the environmental and community impact, the hybrid approach also provided cost savings through reduced fuel usage and servicing intervals.
At Wernick Power, we’re dedicated to providing the most advanced power solutions. We utilise Greener Power’s state-of-the-art battery units and Wernick Power’s Stage V engines, placing us at the cutting edge of the industry. Together, we are able to achieve unparalleled efficiency and reliability while minimising fuel consumption and carbon emissions. We’re also dedicated to making worksites, especially those in rural areas, more neighbour-friendly by reducing noise pollution, all while contributing to a healthier environment.
